Damocles

Damocles (pronounced dam-uh-kleez)

As Sword of Damocles, any situation threatening imminent harm or disaster.

Circa 300 BC: From the Ancient Greek name Δαμοκλῆς (Damoklês).  The most commonly used derived form is the adjectival Damoclean.  There is a school of thought no initial capital is demanded except when referring to Damocles himself.

In mythology

In Classical mythology, Damocles was a sycophantic courtier at the court of King Dionysius II of Syracuse.  Damocles was heard to say Dionysius must be very happy  living the life of a king and on hearing of this, the ruler offered to let him live like that for a day.  Delighted, Damocles accepted and was placed on a throne, attended by servants serving him the finest wines at a most lavish banquet.  Hours into the feast, Damocles chanced to look up and saw, just above his head, a razor-sharp dangling sword, suspended by a single strand from the tail of a horse.  Shocked at the risk to his life, Damocles asked the king why the blade was there.  Dionysius explained it was so Damocles might fully experience the life of a king, including the constant sense of danger powerful people must endure.  Damocles asked to be excused from the feast and be allowed to return to his humble station; the king granting his request.  The original meaning from Antiquity, the sword symbolizing the constant threats powerful people face, has changed over time, now referring to any looming threat, not just those afflicting the rich and powerful.

Long thought apocryphal, legend has it the story was in a lost history of of Sicily by Timaeus of Tauromenium (circa 356–260 BC) and it’s speculated Cicero may have read it in the works of the (1^st century BC) Greek historian Diodorus Siculus for he included it in his Tusculanae Disputationes (Tusculan Thoughts (45 BC)), a five-part treatise of Greek philosophy discussing: the contempt of death; pain; grief; emotional disturbances; and whether virtue alone is sufficient for a happy life).  It was from here the phrase entered classical languages, the Roman lyric poet Horace (Quintus Horatius Flaccus, 65-8 BC) exploring the theme in the Third Book of Odes (23 BC), noting none could be happy "above whose impious head hangs a drawn sword (destrictus ensis)."  It became part of modern European languages after the myths of antiquity were widely published after the Renaissance.  William Shakespeare (1564–1616) explored the theme in Henry IV, Part 1 (circa 1596), Geoffrey Chaucer (circa 1344-1400) used the phrase in The Canterbury Tales (1386-1400) and sixteenth & seventeenth century works sometimes explained the story using the words metus est plenus tyrannis (a tyrant is always fearful).  During the Cold War, both John Kennedy (JFK, 1917–1963; US president 1961-1963) and comrade Khrushchev (1894–1971; Soviet leader 1953-1964) described nuclear weapons as Damoclean although JFK was lamenting the threat they posed to humanity whereas comrade Khrushchev was more bullish, telling the West the USSR’s newly tested fifty-plus megaton hydrogen bomb would "hang like the sword of Damocles over the imperialists' heads".

Comrade Khrushchev's Damoclean sword: A depiction of 30 October 1961 test of Soviet AN-602 hydrogen bomb (Царь-бомба (Tsar Bomba, known also by the Soviet code names Ivan or Vanya (the Pentagon preferred Tsar Bomb)).  The most powerful nuclear weapon ever detonated, the design was technically capable of being able to be produced in a form which would have yielded some 100 megatons but the Soviets built it in smaller form (1) to reduce fall-out and (2) the bomber would have time to escape from the critical blast zone.  For a long time the US estimated the yield at 54 megatons and the Russians at 58 but after the fall of the Soviet Union in 1991, it was confirmed the true yield was 50-51 megatons.
